The first flight of SpaceX’s Dragon capsule

SpaceX plans to launch an unmanned test model of the company’s Dragon crew capsule Wednesday on a whirlwind 107-second flight through the skies over Cape Canaveral.

SpaceX is preparing Thursday for its third attempt to launch the Astra 1P satellite to geostationary transfer orbit (GTO) on behalf of one of its oldest customers: Luxembourg-based SES. Liftoff from pad 40 at Cape Canaveral Space Force Station is targeting 5:35 p.m. EDT (2135 UTC) on Thursday, June 20.

A refurbished SpaceX Crew Dragon spaceship linked up with the International Space Station early Saturday more than 260 miles above Earth, delivering four veteran astronauts to the orbiting research complex and temporarily raising the lab’s crew complement to 11.
